NSA and CIA are watching porn

No, I am not kidding, and you are reading it correctly. Agents from both NSA and CIA are tasked to watch videos including porn. The reason behind this is simple, Al-Qaeda and ISIS (Islamic State) send coded messages to their followers using pornography, reddit, twitter and any other way or social media suits their needs. Israeli Intelligence Agency noticed those messages terrorists are sending using images and videos with the technique called steganography. Steganography is the art/method to hide a message/file in another message/file. For example a shopping list that can contain a secret message, an image that can contain another file or image and so on. The advantage of steganography versus cryptography is that the message is publicly available to everyone and it doesn’t attract attention. I will show you a real example at the end of the article. Back to our news, CIA and NSA are watching nude photos and porn videos to find those message. Of course, terrorists are also using cryptography, advanced cryptography to avoid (delay as far as possible) decryption even with NSA supercomputers. Those nude pictures agents are watching all day long is not only from known terrorists but from everyone, they have surveillance programs were they capture almost anything so think twice the next time you will take a nude picture of your… self.

Landscape

So, now the time for the scary but cool fact. I am sure you’ve noticed the above image of this lovely landscape that is irrelevant to the news. You are wrong, it is relevant! Download the image to your PC by right-click and save image. Now open this file with an archive application like 7-zip, WinZip, WinRar and you will see the secret file that I’ve embedded, a text file pointing to this website. I don’t believe that there is a person without a relevant application but in the strange case you are one of them, rename the file from .jpg to .zip and open it. Even if this looks advanced and difficult it is not, this one is the simplest way of hiding a file in another file. Another steganography technique is that the color of every 100th pixel points to a character in the message you want to send. A message publicly available but not visible if you are not looking for it.
